A strength of plasicity?

-Seasonal plassticiy occures in response to environmental changes -Tramontin found that the SCN shrinks in spring and expands in autumn in songbrids -Signficiant bc it provides further evidence that the brain is constantly adapting, even throughout the year -Limitation is that it is conducted on animals, cannot extrapolate and generalise the findings to human beings due to being a differnece in behaviour, cognitive functioning and size and structure of their brains.
